[tex]\\ \sf\longmapsto y^{24}-256=0[/tex]
[tex]\\ \sf\longmapsto (y^4)^6-256=0[/tex]
[tex]\\ \sf\longmapsto x^6-256=0[/tex]
Or
[tex]\\ \sf\longmapsto x^6=256[/tex]
Answer:
[tex] {y}^{24} - 256 = 0 \\ x = {y}^{4} \\ y = \sqrt[4]{x} = {x}^{ \frac{1}{4} } \\ then \: { {x}^{ \frac{1}{4} } }^{24} - 256 = 0 \\ {x}^{6} - 256 = 0 \\ {x}^{6 } = 256 \\ x = \sqrt[6]{256} = 2.5 \\ thank \: you[/tex]
